A no-deal exit from the European Union would deliver a "hammer blow" to the British economy, the head of the CBI has warned.

The business body's director general Carolyn Fairbairn said the country should get behind Prime Minister Theresa May's Chequers proposals as a blueprint for a Brexit deal.

She warned against "throwing everything up in the air" by tearing up Chequers and seeking an alternative solution at this late stage in negotiations, with fewer than 200 days to go to the scheduled date of Brexit in March 2019.

WalesOnline reports the Government has now published more than 50 "impact" papers showing the effect on all of us if we crash out of the EU without a deal.

While several deal mainly with the impact on businesses that will have to change how they import and export goods to and from the European Union, many talk directly to ordinary people.

As the impact statements were published several other people spoke out to highlight other impacts: These include:

France's Europe minister has been speaking at an event in London.

Nathalie Loiseau said reports that British planes and Eurostar trains travelling between London and Paris would be turned back under a "no-deal" Brexit were "correct,.

She added: "If we reach no agreement this is what will happen, among other things."

No guarantees mobile phone charges won't rise

Mobile phone roaming charges could be hiked less than two years after they were slashed across the EU.

Costs were cut in June 2017, meaning there is no extra fee for using a British device on the continent for calls, texts and data.

Operators would not be bound by the agreement if the UK crashes out without a deal.

The biggest companies, servicing 85% of customers - Three, EE, O2 and Vodafone - have no plans to reimpose roaming charges after Brexit.

But in terms of the entire mobile market, "surcharge-free roaming when you travel to the EU could no longer be guaranteed," the government warns.

House prices will plunge

Bank of England governor Mark Carney warned that a no deal Brexit could send house prices plummeting.

He believes that house prices could fall as much as 35% over a three-year period.

Several reports also told the BBC that the Bank governor also told the Downing Street meeting that mortgage rates could spiral, the pound and inflation could fall, and countless homeowners could be left in negative equity.

Passports

Blue passports will start being issued from late 2019.

If you renew your passport between late 2019 and early 2020, you'll be automatically issued with either a blue or burgundy British passport.

After 29 March 2019, if you're a British passport holder (including passports issued by the crown dependencies and Gibraltar), you'll be considered a third country national under the Schengen Border Code.

According to the Schengen Border Code, third country passports must have at least three months' validity remaining.

If you are planning to travel after 29 March 2019, and your passport will be affected by the new validity rules, it is recommended you consider renewing your passport soon to avoid any delay.

We will lose access to space research

The UK will no longer play any part in the development of the Galileo satellite naviation system. Firms and academics here will no longer be able to bid for contracts to supply it or work on academic research for it. Firms that host ground infrastructure for it may no longer be able to do so.

The UK's academics and businesses will also no longer be able to participate in the Copernicus programme to observe the earth through the study of vast amounts of global data from measurement systems.

Cardiff Central MP Jo Stevens said: "It is deeply worrying that the UK will be shut out of some of the most cutting edge research in the world.

"This research provides thousands of high-tech jobs and provides the economy billions every year.

"Theresa May used to say Brexit wouldn't be the end of the world - but actually it could be!

“By walking away from these collaborative projects, we will be isolating ourselves and having to start from scratch, spending a fortune when our European counterparts have already finished the job.”

UK cars won't be automatically 'valid for sale' in the EU

British carmakers and firms supplying car parts from the UK would face more red tape to sell their vehicles and components on the continent.

The paper says: “In a no deal scenario, (European Community) type-approval issued in the UK would no longer be valid for sales or registrations on the EU market.

"EC type-approvals issued outside of the UK, would no longer be automatically accepted on the UK market.

"This means that affected manufacturers would need to ensure that they have the correct type-approval for each market.”

The Best for Britain anti-Brexit group claims this could be "another blow to the motor industry" - which employs thousands of hard-working Brits.

Heartbroken families could be trapped in limbo

Families who are midway through divorce or child custody cases involving another EU country could find themselves trapped in limbo.

If there’s a no deal Brexit, the UK will cease to be part of co-operation between EU family courts on 29 March 2019.

Instead the UK will fall back on legal conventions drawn up in The Hague. But these are complicated and do not cover every area of the law.

The government has advised families with ongoing cases to seek legal advice if they will not finish by Brexit Day.

The technical note says: "Broadly speaking, cases ongoing on exit day will continue to proceed under the current rules.

"However, we cannot guarantee that EU courts will follow the same principle, nor that EU courts will accept or recognise any judgments stemming from these cases.”

Under a similar principle, companies applying to make EU firms insolvent or those seeking to chase small debts could also have to seek legal advice.
